Welcome to The Long Island Dahlia Society's Website!

Frost has ended the dahlias season for 2019.

We are in the middle of the “Big Dig” of the tubers and storing them for winter. Visit the garden again in early summer when the garden is re-planted and blooming once again!

Monthly Meetings

Meetings are held year round, on the third Thursday of the month. Locations of our meetings vary so please check the LIDS Calendar above each month for time and location. Note the July meeting is held on a Saturday in the William Wolkoff Garden.

Most meetings provide a dahlia education session on dahlia care through the seasons. Meeting include coffee and snacks and provide members an opportunity to share dahlia knowledge and obtain advice.

Meetings are open to all and are free to the public.

Saturday Mornings at the William Wolkoff Garden

Most Saturdays during the year our volunteers meet at 9:00 AM at the William Wolkoff Dahlia Garden in Bayard Cutting Arboretum. Check the calendar for specifics.

Volunteers support the garden by preparing the tubers for planting, maintaining the garden during the bloom time, digging up the tubers at the end of season, and preparing them for storage. Each season provides a hands-on dahlia care learning experience, all are welcome.

Work in the garden is followed by coffee and cake at 11:00 am.
